Why are robocalls not solved?

I suspect the answer is, like most things, 'politics'.

So, to me, for instance, take the biggest problem the world currently faces - global heating.

I think everyone knows the two or three things we would need to do to 'solve it': - carbon tax - carbon capture - energy reset/clean/green/conservation/etc.

But it's only partially 'solved', same as robocalls.

There are just too many people making too much money, having too much success, with robocalling to stop it.

Robocalls I assume are profitable to someone. Therefore they will always find a way around blockage.

I have noticed most calls I get, the phone rings I answer, there is silence for a few seconds (maybe just one) where the robocaller detects someone answering the call, then they route it to a human. The human then gives their speal. I will do one of two things:

1) Say "hello, oh yeah I would like that" and then put the phone down near the TV.

2) Just hang up.

If I think it is a SCAM I will usually say something like, "you should be ashamed of yourself".

All in all, option #1 tends to work the best. I am now only getting "Extend your car warranty" call every 6 months.

>Do telecom companies not have an incentive to block them?

Yes

>Or even worse is it in their favor to let the calls happen?

Also yes

I think a better question would be, why are they solved in most countries in Europe but not in the US?
